FreeBSD daemon.epm.br 6.1-PRERELEASE FreeBSD 6.1-PRERELEASE #2: Thu Mar 2 09:55:10 BRT 2006 root@daemon.epm.br:/usr/obj/usr/src/sys/CABELO i386
>Description:
During sysutils/fuse-kmod update my workstation freeze and reboot create crash dump, apparently fuse-kmod ports unload old kernel before install new version.
I use striped kernel generic, more SCHED_ULE and PREEMPTION.
